描述

There are times when your database gets filled up with duplicate entries that you may not want. Cleanup Duplicate Meta allows you to check for any duplicates in either the Post Meta or User Meta tables. Then if you want to get rid of them, simply click on the Cleanup button and Cleanup Duplicate Meta deletes the duplicates leaving either the first or last meta (you select which).

The interface is simple and easy to use:

  1. ‘Check for Duplicates’ queries the database and then displays all the duplicates found.
  2. ‘Count Duplicates’ counts all the duplicates found in the database (i.e. a total count).
  3. The ‘Cleanup’ buttons trigger a SQL query to run, which deletes each of the duplicate entries, leaving either the first or last one (per your selection) in the database. All non-duplicates remain untouched by the plugin.

See the screenshots tab for more details.

  • Screen for both the Post Meta and User Meta controls.
  • An example of the table generated when clicking on 'Check for Duplicates' button. The results are sorted by meta key.
  • After clicking on the 'Count Duplicates' button, notification is displayed of the number of duplicates found (which could be deleted).
  • The message after clicking on 'Cleanup Post Meta'.

安裝

From your WordPress dashboard

  1. Visit ‘Plugins > Add New’
  2. Search for ‘Cleanup Duplicate Meta’
  3. Activate Cleanup Duplicate Meta from your Plugins page.

Once Activated

  1. Go to ‘Tools > Cleanup Duplicates’
  2. Click on the ‘Check for Duplicates’ button for either Post or User Meta.
  3. If there are duplicates, you can then click on ‘Cleanup Post Meta’ or ‘Cleanup User Meta’ button.

常見問題

How do I check how many duplicates are in either the Post Meta or User Meta table?

Simply click on the ‘Check for Duplicates’ button and the plugin will report the count back to you on the screen.

See the screenshot 2 for an example.

How do I know whether to leave the first or last one?

If you know which one you want, then select either the first or last one. Otherwise, leave it at the default.

Should I backup my database first?

Yes. Before you run Cleanup, you should backup your database.

Will this work on WordPress multisite?

Yes!

What happens to non-duplicates when I run Cleanup?

Nothing. Cleanup Duplicate Meta does not touch non-duplicates. Therefore you’re data remains intact.

Wow! It saved my site!

I had over a million duplicate post meta entries from Avada (Theme Fusion). It shrinked my wp_postmeta table to 1/10 of the original size. Thank you and please update your plugin.

Works perfect

Cleaned up nearly 70,000 redundant _postmeta records with just a couple of clicks. Top marks.

Still works

This plugin helped me remove 31195 Duplicate records in the wp_postmeta database table. Most were ACF fields, i don't know why they are there but some posts had up to 8 times the same field... It also helped me find old meta by old plugins i don't even remember using so i was able to delete all of those (the originals too) with phpmyadmin. It shaved 10 MB of wp_postmeta!

Old but works!!

Really handy plugin
